Hi, I have a question.
CLKA = 2 × CLKB
Signal in CLKA domain is active for 2 CLKA cycle.
At clock domain crossing we have used 2 bit synthronizer,
At synthronizer output, how many CLKB cycles it will have . ??
options:
(1) 1
(2) 2
(3) 3
And Also , for this MCD scenario, 2 bit synthronizer...
Hi,
Thanks for the reply.
My question is :
if i have to communicate the count of the 4 bit counter to the other clock domain, the domain.
the follong circuit is correct for 15-0 detection
OR it should be posed detection at the AND GATE .
Hi
I have problem:
question:
4 bit binary counter(0 to 3) , counts increments from 0 to 15 in clock A domain.
now the count has to be communicated in the other clock domain clock B using edge detection circuits.
what will be the ciruit will it use to detect count 2-3 . &
what will be the...
min fifo depth same frequency different phase
Thanks for ur reply.
thats true, if i take this approch i will get the FIFO depth of 16?
since the frequencies are same i do not need to put the synthronizer, hence synchronizer latency (usually 1 clock cycle)will not be there
Thanks in advance,
fifo depth design
Hi,
I need to provide the delay of 16 clock cycle, using FIFO.
if write frequency and read frequency is same and phase is also same,
then FIFO Depth should be ?
options are :
(1) 16
(2) >16
(3) <16
Thanks for anticipation !!
